This example loads a named CSS color dataset from a remote CSV file and displays a summary of its size, row count, and column count. The React component uses the `useState` hook to store the data after fetching it asynchronously with d3.csv. The message is computed by formatting the CSV data back into a string with `d3.csvFormat`, measuring its length, and counting rows and columns. The interface shows only the text summary, with no graphic or interactive element beyond the loading state.
